BACKGROUND OF THE DISCLOSURE

Hospital operating rooms typically include surgical equipment and one ormore lights that are located over a surgical site. The surgicalequipment may be movable in relation to a surgical site target zone.

Additionally, air supply arrangement may be positioned within a ceilingdirectly above the surgical light and the surgical site target zone. Theair supply arrangement may include vents through which filtered air issupplied and directed toward the surgical site. Sidewall vents returncontaminated air from the perimeter of the room to an air filtrationsystem positioned upstream of the supply air array. The air filtrationsystem supplies filtered air to the room through the supply air arraywith unidirectional, downward airflow.

Because the surgical equipment (e.g., surgical light) may be positioneddirectly over the surgical target zone, the surgical equipment may blockairflow generated by the air supply arrangement and create a lowpressure zone underneath the surgical equipment. The low pressure zonecauses air turbulence underneath the surgical equipment. Due toturbulent airflow, various contaminants generated through a surgicalprocedure may be circulated within the surgical environment. Forexample, surgical staff may carry particulate and bacterial contaminantsthat may be dispersed directly above a surgical site in the absence offiltered, downward, unidirectional flow. Further, bone fragments,biological fluids, and blood may be projected upward toward the surgicalequipment, which is cleaned and sterilized between surgical procedures.

Accordingly, a need exists for a system and method of providinguninterrupted, reduced turbulence airflow within a sterile field andunderneath surgical equipment. A need also exists for a system andmethod that reduces the possibility of contaminants being dispersed overand within a surgical site.

DETAILED DESCRIPTION OF THE DISCLOSURE

The foregoing summary, as well as the following detailed description ofcertain embodiments will be better understood when read in conjunctionwith the appended drawings. As used herein, an element or step recitedin the singular and preceded by the word “a” or “an” should beunderstood as not necessarily excluding the plural of the elements orsteps. Further, references to “one embodiment” are not intended to beinterpreted as excluding the existence of additional embodiments thatalso incorporate the recited features. Moreover, unless explicitlystated to the contrary, embodiments “comprising” or “having” an elementor a plurality of elements having a particular property may includeadditional elements not having that property.

Certain embodiments of the present disclosure provide an airflow systemthat includes a frame structure that allows for proper airflow withinthe surgical target zone even when surgical equipment is positionedabove the surgical target zone. For example, in various embodiments, lowpressure zones that could cause air turbulence underneath the surgicalequipment are reduced or eliminated. As such, in various embodiments,because the turbulent airflow is reduced or eliminated, variouscontaminants generated through a surgical procedure are not circulatedwithin the surgical environment.

One or more embodiments provide an airframe structure that is configuredto channel air, which may be filtered, sterilized or purified, to thesurgical target zone with minimal or no air turbulence underneath thesurgical equipment. Various embodiments provide an integrated andmodular arrangement to effectively deliver airflow directly to thesurgical target zone.

FIG. 1 illustrates a lateral view of an operating room 10, according toan embodiment of the present disclosure. The operating room 10 may bedefined by walls 12, a ceiling 14, and a floor 16. An operating table 18may be supported on the floor 16. The operating table 18 may include asupport bed 20 that is configured to support a patient 22. A surgicalsite 19 may be located on the patient 22.

Surgical equipment, which in the illustrated embodiment is a surgicallight system 100 is suspended from the ceiling 14 above the operatingtable 18, which may define a sterile field 30. A support beam 102extends downwardly from the ceiling 14. One or more boom arms 104 mayextend from the support beam 102. As shown in FIG. 1, two surgical lightassemblies 100 may be coupled to two separate and distinct boom arms104. Alternatively, more or less surgical light assemblies 100 thanshown may be used. It should be appreciated that surgical light system100 is shown only for illustrative purpose and different or additionalsurgical equipment may be suspended from the ceiling 14.

A supply air array 106 (also referred to as an air frame system) issecured to the ceiling 104. The supply air array 106 is configured todirect airflow into the operating room 10 and in various embodimentsdefines a supply air frame. The supply air array 106 may include one ormore air diffusers 108 (or air delivery modules). Additionally, one ormore return vents 110, which may be secured to one or more walls 12 areprovided. In the illustrated embodiment, the supply air array 106directs airflow into the operating room through the diffusers 108. Theairflow passes into the return vents 110, which channel the airflow backinto the supply air array 106, where the airflow is filtered anddirected back into the operating room through the air diffusers 108. Asdiscussed in more detail herein, the supply air array 106 is configuredto control airflow in operating room 10 such that air is directed fromthe sterile field 30 to a non-sterile field 32 without beingrecirculated back into the sterile field 30. Thus, airflow is directedfrom the supply air array 106 into the sterile field 30 then to thenon-sterile field 32 and finally into the one or more return vents 110.

The supply air array 106 is also configured to include an integratedlighting structure that includes a plurality of light sources asdescribed in more detail herein. Accordingly, in various embodiments thesupply air array 106 defines an integrated unit that may be installedwith electrical components and air supplies connected to a singlestructural element. Thus, a laminar airflow is created directly to thesurgical target zone that creates an airflow pressure to reduce orprevent turbulence, which is also being lit by the integrated lighting.

FIG. 2 illustrates a perspective bottom view of the supply air array106, according to an embodiment of the present disclosure. The supplyair array 106 in the illustrated embodiment includes a lower frame 200having a plurality of openings 202 defined therein by cross-members 204and 206. It should be noted that although the illustrated embodimentshows a 2 cell×4 cell array, the supply air array 106 may be sizeddifferently, including having a single opening 202. Additionally, theopenings 202 may be sized and shaped differently than illustrated, forexample, based on design requirements or constraints. In the embodimentshown in FIG. 2, the front four openings 202 are illustrated withnothing therein and the back four opening 202 illustrate air diffusers108 coupled within the openings 202. As can be seen, the air diffusers108 are coupled with the openings 202 such that the air diffusers 108are recessed within the openings 202 in this embodiment.

FIG. 3 illustrates a perspective bottom view of the supply air array 106in which all of the openings have air diffusers 108 coupled therein andshows that the air diffusers 108 may be hingedly mounted to one side ofthe openings 202 such that access may be provided within the openings202, as well as to both sides of the air diffusers 108 (e.g., to cleanthe air diffusers 108 or to install HEPA filters). As can be seen inFIG. 4, a top cover 220 is coupled above the lower frame 200 (e.g., byan airtight seal) to define a pressure air space above the lower frame200. In the illustrated embodiment, an air coupler 222 is provided onone end of the top cover 220 to allow coupling to an air supply thatprovides airflow into the top cover 220. The air coupler is made up of asupply air passage 201 and a supply air connection flange 230. There maybe more than one air coupler 222 which may be positioned at any locationon the top, the sides or the ends of the top cover 220. In operation,air supplied into the top cover 220 is directed into the sterile field30 (shown in FIG. 1) to define a non-turbulent laminar flow.

FIGS. 4 and 5 are elevation views of the supply air array 106 and FIG. 6is a bottom plan view of the supply air array 106. In the illustratedembodiment, an air supply connection 230 may be provided that includes acleansing system, shown as a sterilization system 232. As discussedherein, the cleansing system may include an air filtering system, thesterilization system 232 and/or an air purifying system. The cleansingsystem may be placed at any location within the supply air array 106 orupstream of the supply air array 106. The cleansing system is positionedup stream of the opening 202 such that air that passes through theopening 202 is cleansed.

The supply air array 106 includes an adjustable mounting arrangement 240that allows for varying the height of components, such as the boom arm102 mounted within the openings. In particular, the adjustable mountingarrangement 240 defines mounting locations within the each opening 202of the lower frame 200. The adjustable mounting arrangement 240 in theillustrated embodiment includes a mounting plate 242 that may be mountedwithin the opening 202 at different locations, in particular, differentvertical locations within the opening 202. For example, predefinedmounting locations (e.g., mounting bores) may be located on opposingwalls of the opening 202 for coupling thereto of the mounting plate 242(e.g., bolt mounting of the mounting plate 242 to walls of the opening202). The predefined mounting locations provide a coarse mountingarrangement within the opening 202. For example, as can be seen in FIG.5, the two mounting plates 242 are mounted at different vertical heightswithin respective openings 202.

The mounting plates 242 couple to a secondary plate 244 that allows foradjustable mounting thereto of a bottom plate 246. For example, pluralbolts 248 may couple the secondary plate 244 (or intermediate plate) tothe bottom plate 244 to allow finer height adjustment within the opening202. As can be seen in FIG. 5, the bottom plate 244 in the differentopenings 202 extend a different distance from the secondary plate 244such that the bottom plate 244 in each of the openings 202 is positionedat different vertical heights. As should be appreciated, components tobe mounted within each of the openings 202 may be mounted at the same ordifferent vertical heights.

As shown in FIG. 6, the cross-members 204 and 206 define an airtightarrangement wherein airflow is directed around the cross-members 204 and206 into the openings 202, which will be described in more detailherein. Additionally, separate lower frames 200 may be coupled togetherat a seam 250. For example, in the illustrated embodiment, a lower frame200 a defining a 2 cell×5 cell supply air array 106 is coupled with alower frame 200 b defining a 1 cell×5 cell supply air array 106. Thelower frames 200 a and 200 b may be coupled together using any suitablefastening arrangement, such as coupling together by bolts.

As illustrated in FIGS. 7 and 8, different modular elements (shown asthree different types of modular units) defining the openings 202 in thesupply air array 106 may be coupled together with a bolted connection260 or a welded connection 262. Thus, different sized and shaped supplyair arrays 106 may be provided that include different types of modularelements. The different types of modular elements may include differentelements, such as the diffusers 108, lights or other components thatwould be desirable or needed in the operating room 10. In someembodiments, the supply air array 106 may include the lower frame 200with components, a light housing with components, a wireway withcomponents and/or a hinged screen and airflow control damper (such asthe airflow dampers 108). In various embodiments, plural air diffusers108 are installed with the top cover 220 having a top or side mountedair duct collar.

FIG. 9 illustrates a single modular element 300, according to anembodiment of the disclosure. The modular element 300 is defined by theopening 202 between supporting members, which in this embodiment arehollow structural section (HSS) tube frames 302 that may be mounted, forexample, to a truss system, such as described in co-pending patentapplication entitled Equipment Support System and Method of SupportingEquipment in a Surgical Environment, filed on Oct. 7, 2016 and havingAttorney Docket No. 168008, or to the ceiling 14. The HSS tube frames302 may include a snap-fit light assembly 304 coupled to the HSS tubeframes 302 (illustrated as coupled with a bolt). The light assembly 304may be a suitable light source for an operating room environment andinclude a light lens 316 at a bottom surface thereof.

In the embodiment of FIG. 9, the air diffuser 108 includes a screen 306and a damper 308 (also shown in FIG. 17) that extend across the opening202, which may be adjusted (e.g., rotated) by a tool, such as an Allenwrench, causing the damper 308 to open or close (in a guillotine typeconfiguration). The screen 306 and damper 308 are coupled together as asingle unit and hingedly coupled to one end of the opening 202, forexample, to a lower end of an airframe channel 402 in which the lightassembly 304 is coupled. The damper top plate 307 and damper 308arrangement includes a damper adjustment mechanism 312 that allows formovement of the damper top plate 307 and damper 308 relative to eachother to adjust airflow therethrough. Thus, an airflow control dampermay be defined.

As can be seen in FIG. 10, an air cleansing member, illustrated as anair filter 314, such as a high-efficiency particulate arrestance (HEPA)filter may be provided. The air filter 314 is removably coupled withinthe opening 202 to allow for removal and replacement within the opening202. For example, a knife edge seal and HEPA lock may be provided asillustrated in FIG. 12.

Various embodiments, thus, provide air delivery and lighting in amodular, easily to install configuration. In various embodiments, anairframe system 350 may be provided, components of which are shown inFIG. 11. The components may be coupled together in differentconfigurations as desired or needed, and as discussed herein. FIG. 11illustrates base components in accordance with some embodiments.Illustrated in FIG. 11 are portions of various components, thecomponents include a portion of a lighting module 352 (shown in anexploded view, the elements of which couple together without fasteners)and portions of air delivery modules 352, which may be sized and shapedbased on a particular configuration. In various embodiments, the modulesdefine separate systems or sub-systems to deliver the differentfeatures, including lighting and air. As illustrated in FIG. 12, thelighting module 352 is coupled to air delivery modules 352 (to define alighting and air delivery sub-system) that is integrated with one ormore structural mounts 356, such as by mounting these componentstogether in a desired arrangement or configuration. It should be notedthat in various embodiments, there is no penetration into the lightcavity (e.g., inside the lighting module 352) as a result of the rivetholes for mounting being located in the airframe.

With reference now to FIGS. 13-16, various elements of the structuralsupport for the supply air array 106 will now be described. Inparticular, the HSS tube frame 302 may be coupled with a light housing400 (which may be embodied as the lighting module 352) having upperengagement members 304 and lower engagement member 404 that provide asnap fit coupling with the light assembly 304 and the lens 316,respectively (without the need for hardware fasteners). Additionally,the light housing 400 may be coupled with airframe support members 402(which may be embodied as the air delivery modules 354) that are mountedto a support structure, such as the wall 12 or ceiling 14 of theoperating room 10. The light housing 400 with the airframe supportmembers 402 together define air frame channels of the supply air array106. Variations and modifications are contemplated. For example, in someembodiments, a thumb tab release is provided in combination with aretainer clip 305 within the light housing 400 for easier removal of thecomponents within the light housing 400.

For example, as shown in FIG. 13, the light housing 400, which isillustrated as a light bar, includes mounting tracks, illustrated asrivet tracks 401 (illustrated as grooves extending longitudinally alongthe outer walls of the light housing 400) to which the airframe 402 iscoupled by a rivet 403. As should be appreciated, the rivet tracks 401allow the airframe 402 at any suitable location along the light housing400. A HEPA lock 405 may be provided on the airframe 402 (illustrated asa locking arm coupled within the airframe 402) that allows forreleasably securing a HEPA filter (or other filtering device) within theairframe 402 as discussed in more detail herein.

With respect to the light assembly 304 that is coupled within the lighthousing 400, a control housing 404 is coupled to an LED board 406 (lightsource) and is configured to receive therein a light controller 408. Awireway plug 410 is coupled to the bottom of a wireway cavity 303. Abolt 412 couples the light housing 400 to the HSS tube frame 302. Thecontrol housing 404 is configured with male protrusions 405 for snap fitengagement with an upper female cavity 301. In particular, the width ofthe light housing 400 narrows from bottom to top (as viewed in theFigures) such that control housing 404 is compressed and snap fittherein engaging the male protrusions 405 into the female cavity 301.

With reference now to FIGS. 18 and 19, the supply air array 106 includesthe lower frame 200 that defines an air frame 402 with plural airpassages 450 (airflow openings) along an inner edge 452 of each of theopenings 202. For example, plural spaced apart openings 450 formedaround the periphery of the opening 202 define airflow outlets. Theplural air passages 450 allow airflow therethrough, which is directed atan angle downward, for example, by the size, shape and orientation ofthe air passages 450. Thus, the air passages 450 are configured todirect airflow at an angle downward underneath the light housing 400.For example, an airflow outlet through the plural air passages 450 maybe formed within the airframe directly adjacent to the periphery of adiffuser screen 460 as shown in FIG. 20 to direct airflow as shown bythe arrows AF in FIG. 21. The airflow directed through the air passages450 creates a pressure zone underneath the light housing 400 allowingfor consistent pressure and airflow beneath the entire supply air array106.

In some embodiments, a light diffuser structure may be formed inaccordance with disclosure herein. For example, FIG. 22 illustrates a2×2 light diffuser 500 and a 2×4 light diffuser 502. However, as shouldbe appreciated, different sized configurations of light diffuser may beprovided.

Thus, various embodiments provide an air frame structure that caninclude lighting, wherein an air conduit is provided within the airframe structure to direct air into the sterile field 30. The variousembodiments allow for the integration of multiple components into aneasy to install and customizable system 600, such as shown in FIG. 23.The components may be formed or defined by modules or sub-systems thatare coupled together as described herein. In the illustrated embodiment,the system 600 can include one or more air delivery modules 602, one ormore lighting modules 604 (illustrated as LED lighting modules), one ormore fire suppression modules 606, one or more audio/video modules 608and one or more structural mounts 610, as described in more detailherein. Structural mounts may be configured as a single cell, Flex mount610 or as a multiple cell arrangement 612. In the various embodiments,with a pressurized module (which may be embodied as or form part of thetop cover 220 (shown in FIG. 3) that allows for simple and easy airsource hook-up (e.g., contractor hook up, such as a single or dual S/Aconnection) and having improved quality and performance. The system 600,thus, provides single point air source connection instead of multipleconnection points, resulting in less potential for air loss, lesssealing and lower complexity. The system 600 also provides highperformance controlled airflow, which includes controlling contaminants(that can be beneficial, such as to protect a patient in an operatingroom having the system 600 installed), using the plurality of modules asdescribed herein.

It should be noted that in the system 600, the structural mounts 610 maybe located (e.g., mounted) along the perimeter of the system 600,thereby being located along the perimeter of the airfield. In thisconfiguration, air flow within the airfield is improved by not havingthe mounts within the portion of the system 600 that includes theairfield. It should also be noted that field connections can be madeprior to equipment installation, thereby providing improved access forservices, such as for power, data, audio/video, lighting andcommunications, among others. In some embodiments, one or more of themodules may include interface of connectors, such as a MedGas manifoldwith field piping performed prior to equipment installation.

Various embodiments also allow single trade, single sourceresponsibility of the system, instead of multiple trade, multiple sourceresponsibility. In various embodiments, the airframe members 402, suchas of adjacent modules, are mounted in abutting engagement as shown inFIG. 24.

As should be appreciated, the number and location of each of thesemodules may be varied as desired or needed, such as based on theparticular application or environment. For example, a plurality ofmodules may be installed for a particular environment that includes easyload HEPA (see FIG. 25 showing a HEPA filter 652 locked into place witha HEPA lock 650 in combination with an airframe knife edge seal 654) andeasy clean damper/diffuser features as described herein, such as using ahinged access configuration as described herein. Additionally, in someembodiments, single cell flex mount modules may be provided, which areconfigured like the structural mounts 610 and having bolt-oncapabilities (e.g., bolt-on fastening or connection to another module,which allows for flexible and movable mounting locations and positions.

In various embodiments, multiple attachment points are provided permodule (e.g., four attachment points per module). In these embodiments,anchoring installation time is reduced, which in some cases, is thirtytimes faster than conventional system installations.

Thus, as shown and described herein, various embodiments, including, forexample, the supply air array 106 is configured to direct pressurizedair underneath an entire lower surface of a frame structure thatincludes easily removable light assemblies. The pressurized airunderneath the supply air array 106 reduces or eliminates turbulentrecirculation of contaminants directly over the patient and surgicalsite. The air passages 450 direct air under the light housing 400 or anyspace between the airframe members 402. The pressurized air under thelight housing 400 reduces or eliminates turbulent recirculation of airthat might entrain contaminants.

Variations and modifications to the various embodiments arecontemplated. For example, one or more of the structural elements orcomponents of the embodiments described herein may be modified oradditional elements provided, such as illustrated in FIGS. 26-33. Themodifications shown relate generally to the airframe system 350described herein. As should be appreciated, the components may becoupled together in different configurations as desired or needed, andas discussed herein.

More particularly, FIG. 26 illustrates a full grid assembly 700 inaccordance with an embodiment. The arrangement allows for easilyinstallation and mounting of various components, such as coupling alighting module to the structure of the assembly 700. The assembly 700generally includes mounting, positioning and alignment components thatfacilitate the installation of the assembly in various embodiments. Inthe illustrated embodiment, the assembly 700 includes a support portion702, which forms part of the support structure of the assembly. In oneexample, the support portion 702 is a support beam or tube, such as aHollow Structural Section (HSS) tube. In some examples, the supportportion 702 is metal (e.g., steel) having a hollow tubularcross-section. However, it should be appreciated that the supportportion 702 can be sized and shaped differently. For example, thesupport portion 702 can be configured as an HSS member having differentshapes, such as circular, square, rectangular or elliptical. It shouldbe appreciated that different support structures or elements can beused, including support structures having different hollowconfigurations or non-hollow configurations.

In the illustrated embodiment, the support portion 702 is positioned ata perimeter of a module and may be embodiment, for example, as the HSStube frame 302 described and illustrated herein. It should be noted thatthere is no light element under the support portion 702 in theillustrated example. The support portion 702 is configured to couple to(e.g., bolt through) to an adjacent module that has a light element. Forexample, the support portion 702 is coupled to a support portion 704using a fastener, illustrated as a bolt 708. The support portion 704 inone example is another HSS member, illustrated as an HSS tube. In theillustrated configuration, the support portion 704 is larger than thesupport portion 702, both in width and height. The dimension of thesupport portions 702 and 704 may be varied as desired or needed and therelative dimensions are shown as an example. In one configuration, thesupport portion 702 is a 1×3 HSS tube and the support portion 704 is a2×4 HSS tube. The support portions 702 and 704 define a supportstructure for the assembly 700 and include a seam 706 (module seam)therebetween. In one example, the support portion 704 includes a lightelement thereunder, such that in a grid arrangement, at one or moreseams 706, one side includes a light element and the other side does notinclude a light element.

The assembly 700 also includes an air filter frame, illustrated as aHEPA filter frame 710. The HEPA filter frame 710 is configured toreceive therein and/or house a HEPA filter media. It should beappreciated that different filter elements may be used as desired orneeded, such as based on filtering requirements. In one example, theHEPA filter media is installed in the system to filter out contaminants.For example, the HEPA filter media is installed from below the assemblyand lifted into place as described in more detail herein. In oneexample, is a gel filled trough 712 in the HEPA filter frame 710 sealsto a knife edge track 728 once installed and as described in more detailherein. In one example, the knife edge track 728 is formed into a frameof four sides with a top that has been welded and sealed with caulking.The knife edge track 728 in the illustrated embodiment faces downward atthe top of the frame and penetrates the gel (not shown) within the HEPAfilter trough 712 in order to seal the system. In one configuration, aplurality of air passages is provided at the bottom of the track toallow air to be introduced under the light grid at a 45 degree angle asdescribed in more detail herein.

The HEPA filter media is held in place with a plurality of filter locks714, which in one embodiment includes four HEPA locks. The filter locks714 in one example have a length greater than a width and are operableto rotate to lock and unlock the HEPA filter media. For example, thefilter locks 714 are rotatable ninety degrees in one example to swingunder the HEPA filter media once in place to hold the HEPA filter mediain position.

The filter support arrangement further includes a filter lock angle 716,illustrated as corner support that holds the filter locks 714 to theassembly 700. In one example, the filter lock angle 716 is secured tothe assembly using fasteners, such as screws 718. Thus, the filter lockangle 716 is screwed to the assembly 700 in some examples using sheetmetal screws (e.g., screw the filter lock angle 716 into the airframegrid described herein). As can be seen, the screws 718 are shielded by awireway channel leg 720 to prevent any wires running through the griddefined by the assembly 700 from getting cut by the screw 718. Thus, inthe illustrated example, the wireway channel leg 720 provides a boundaryfor the sheet metal screw 718 in order to protect the wiring within anairframe grid 722. The wireway channel leg 720 also provides a wall thatcreates a wireway channel 726 allowing for a snap in channel cover clip,illustrated as a wireway channel cover clip 724 to enclose the wires(not shown) therein.

In one example, the wireway channel cover clip 724 defines a profilethat can snap into the wireway channel 726 in order to enclose a wire orgroup of wires therein. The wireway channel cover clip 724 acts as aboundary between the wires in the channel and other wires within thesystem. The wireway channel cover clip 724 in one example is configuredas a cover and runs the full length of the airframe grid 722 to fullyenclose the wires within. As another example, the wireway channel coverclip 724 cab be cut into smaller pieces to hold the wire in place,thereby defining a clip structure. The airframe grid 722 in variousexamples is configured to house all the wiring and lighting components.The airframe grid 722 (configured in some embodiments as a light bar)also acts as a fixing element to attach the structural framing and theknife edge track 728 thereto.

It should be appreciated that additional wireway channel cover clips 724can be provided to cover other wireway channels 726, such as along sidesof the structure as shown in FIG. 26. In the illustrated embodiment, thewireway channels 726 are longitudinally extending channels and can besized and shaped as desired or needed. In the illustrated embodiment,three wireway channels 726 are shown that allow for wires to runtherethrough without interference from other components placed into thesystem. The three wireway channels 726 in one example allow forseparation of high voltage, low voltage, control signal, audio, video orother wiring circuits.

The assembly 700 further includes a rivet track 730 extending along anoutside surface of the airframe grid 722. In the illustrated embodiment,the rivet track 730 is configured to allow for attachment of the knifeedge track 728 (illustrated as an airframe knife edge track) to the grid722 or for other components such as a perimeter angle. Additionally, inone example, a seal track 732 (extending along an outside surface of theairframe grid 722) allows for either a wet or dry seal to be appliedprior to assembly. The seal track 732 helps to prevent leaking ofcontaminants after assembly.

The assembly 700 also includes a lighting element 734 in oneconfiguration. In one particular example, the lighting element an LEDboard or module that provides lighting thereunder (e.g., lights a spacebelow). In one embodiment, the lighting element is coupled to a strut736, illustrated as an LED strut, with fasteners, such as screws thatpenetrate into a screw boss in the strut 736. This arrangement isconfigured to keep the screws from engaging any wiring directly, whichcould strip the wire and cause a short. This arrangement also allows fora faster assembly of the components.

With respect to the strut 736, this component is configured in theillustrated example to provide several functions. In particular, thestrut 726 is the primary attachment method for the lighting components.The lighting element 734 is screwed to the strut 736. Additionally, thelighting drivers, such as the LED drivers can also be screwed to thestrut 736. The strut 736 in one example is formed with threads in theextrusion so that the lighting element 734 (e.g., LED board) is easilyscrewed down thereto. The above-described design also allows for severalwidths of the lighting element 734 (e.g., the LED board) to be used,with a second set of channels to receive a screw and protect the wiringfrom the sharp threads on the screw. It should be noted that theserpentine shape of the strut 736 allows the strut 736 to act as a heatsync due to the increased surface area in contact with the surroundingair space. This configuration allows heat to dissipate more efficientlyand keeps the LED components cooler. As a result, heat buildup isreduced that can provide a safety feature and increased operating lifeof the LED lighting product.

In one example, airflow equalization passages 738 are provided as aplurality of penetrations at the lower edge of the knife edge track 728.The airflow equalization passages 738 are configured to allow air to beintroduced under the light grid at a 45 degree angle. This configurationprovides for pressure under the light in order to reduce turbulence inthe air stream as described in more detail herein.

The assembly 700 in various embodiments allows for quick and easycoupling of the various components. For example, a bolt, illustrated asa T-nut bolt 740 screws into a T-nut 742 and fastens components to thesystem quickly and easily. In the illustrated embodiment, the T-nut 742is a spring T-nut configured to allow placement of the T-nut bolt 740within a T-nut slot 750 from the top with both ends of the slotcaptured. This coupling arrangement in various embodiments can beprovided with or without the spring. The spring, when included, holdsthe T-nut 742 in place during assembly.

As can be seen more clearly in FIGS. 28 and 29, the strut 736 is easilyinstalled and removed into the airframe grid 722. The strut 736 in oneexample is formed of metal (that acts as grounding in variousembodiments) and configured to house an LED driver 752, as well as holdan LED lighting board 754 in the proper position. The strut 736 in oneexample has a serpentine shape allowing for increased surface area incontact with the surrounding air. As discussed herein, thisconfiguration allows for the dissipation of heat from the airframe gridcavity. In one example, there are two types of screw channels. One screwchannel 756 has threads and the other screw channel 758 does not havethreads. These channels 756 and 758 allow for the installation ofdifferent sized boards 754, such as having two different sizes. Thethreaded channel 756 is configured to couple with a machine screw andthe non-threaded channel 758 is configured to couple with a self-tappingmetal screw, in some embodiments. Both channels 756 and 758 areconfigured in various examples to protect the wiring in the strut 736from the sharp screw threads.

The T-Nut slot 750 is configured to allow fast and easy installation ofthe driver components into the strut 736 as described herein. The T-nut742 (with or without spring) is installed into the slot 750 from the topand includes a threaded hole for bolting. The driver 752 is installedfrom the top and two screws are installed at each end into the T-nut742. The strut 736 is then pushed into the airframe grid 722 until toplegs 760 register with a snap fit into a registration groove 762(illustrated in FIGS. 27 and 30) into the grid 722. A retainer clip 744is then installed to hold the strut 736 into place as described below.

It should be noted that the strut 736 includes a plurality of centerfinders 764 that allow for easier identification of center positions forinstalling screws of other fastening mechanisms. It should be noted thatadditional center finders 764 may be provide and located in differentpositions along any portion of the strut 736. Additionally, fewer centerfinders 736 also may be provided. Also, while the center finders 764 areillustrated as triangular indents, different sized and shaped featuresmay be provided.

In particular, in one example, the retainer clip 744 is arcuate orcurved shaped, such as crescent shaped, so that the retainer clip 744can be installed and removed easily without any tools as described inmore detail herein. The use of the retainer clip 744 in this assemblyrequires no tools or hardware to install or remove the lightingcomponents, such as the LED lighting components. In the illustratedexample, the retainer clip 744 includes a release member, illustrated asa thumb press lever 746 (as seen more clearly in FIG. 27) on the insideportion of the retainer clip 744. In operation, when the retainer clip744 is pushed (such as by applying a force thereto) as shown by thearrows in FIG. 27, the retainer clip 744 is released to allow removalthereof, as well as access to components there-above. As can be seen,ends 776 of the retainer clip 744 are configured to engage grooves 778in the airframe grid 722.

In one embodiment, the retainer clip 744 is formed from a flexiblematerial that can spring into place (e.g., allows biasing). For example,the retainer clip 744 in some embodiment is formed from a plastic orplastic composite material. It should be noted that the retainer clip744 is shown coupled to the assembly 700, but may be used in otherapplications and with other structural support assemblies to provide aretaining feature.

The retainer clip 744 is designed in one example with the thumb presslever 746 being an integral L-shaped thumb tab. The thumb press lever746 is used to apply pressure and grab the clip from below in order toremove thumb press lever 746.

As can be seen more clearly in FIGS. 31 and 32, the grid 722 is shapedto include various wireway channels 726, as well as other channels. Forexample, a screw track 766 is provided that allows for a screw topenetrate the side of the grid 722, such as through the center finder764. It should be noted that in some embodiments other features locatedin positions other than the center can be provided to facilitatefastening connections. For example, additional or different registrationbumps may be provided as desired or needed.

The assembly 700 includes a light lens 748 that is removably coupled tothe assembly 700. In one example, the light lens 748 closes the systemto reduce dust and water ingress and provides light diffusion in orderto reduce glare, but allows an increased or the highest light outputfrom the grid. As can be seen in FIG. 31, the light lens 748 includesretaining wings 768 that are bendable or compressible to allow forremovable coupling of the light lens 748 to the grid 722 as illustratedin FIG. 32. Additionally, the light lens 748 includes a plurality ofribs 770, configured as diffusion ribs along an inner surface of thelight lens 748. The ribs 770 in one embodiment extend along the entiretyof the bottom of the light lens 748 (as viewed in FIG. 31) and along theretaining wings 768.

It should be noted that additional features may be provided. Forexample, as shown more clearly in FIG. 30, a registration feature,illustrated as a registration bump 772 is provided at a top portion ofthe airframe grid 722. In some embodiment, the location and/or shapeand/or number of the registration bumps 772 acts as an identifier of theparticular configuration of the airframe grid 722.

As other examples, a sealing arrangement can be provided as illustratedin FIGS. 33A, 33B, 34 and 35. More particularly, the sealing arrangementin one example includes a gasket channel 780 and the light lens 748 witha gasket 782. In this embodim736ent, when the elements are coupledtogether, a sealed assembly 784 is provided. In particular, the gasketchannel 780 and gasket 782 seal the light lens 748. As can be seen moreclearly in FIGS. 34 and 35, the gasket channel 780 in one embodimentincludes bolts 786 extending from a top of the gasket channel 780 thatallow for coupling to the strut 736.

The gasket channel 780 and gasket 782 can have different shapes andsizes, as well as be formed from different materials. For example, thegasket channel 780 in one example is general C-shaped and covers an endof the sealed assembly 784, as can be seen more clearly in FIG. 36. Thatis, the gasket channel 780 is positioned at an end 788 of the light lens748. In some embodiments, the gasket channel 780 can additionally oralternatively be positioned at a seam 790 between two light lenses 748.

Thus, the assembly 700 that is easier to install and maintain can beprovided, such as illustrated in FIG. 38.
